AMD Phenom II X4 955 Black Edition Deneb Quad-Core 3.2 GHz Socket AM3 125W HDZ955FBGIBOX Processor

Like the superheroes of old, the AMD Phenom II X4 955 streaks out of the night to lay waste to your enemies with four 3.2GH z cores that have dedicated L1 and L2 caches for each, and 6MB of shared L3 cache to handle really heavy loads or large data sets. Memory transfers get faster than ever. HyperTransport Generation 3.0 mode allows up to 16.0GB /s of bandwidth. Up to 17.1GB /s memory bandwidth for DDR2 and up to 21GB/s memory bandwidth for DDR3 memory controller delivers an amazing total of 37GB/s of processor-to-system bandwidth.

This unprecedented bandwidth is needed to feed the data hungry AMD64 with Direct Connect Architecture cores. You'd think that all of this power would be too hot to handle. Think again. AMD's Cool'n'Quiet 3.0 works with CoolCore Technology to minimize heat while keeping power and efficiency up. Now the cores can shut down unused parts of the processor when not in use. This saves power and helps to reduce the amount of heat generated. This function is built in so there's no need for drivers or BIOS updates.
